Factors associated with inappropriate chemical prophylaxis of thromboembolism in surgical patients.

Introduction: Despite various guidelines for venous thromboembolism (VTE) prevention, malpractice in prescribing thromboprophylaxis is common. In this study, factors associated with prescribing or not prescribing appropriate chemical thromboprophylaxis were assessed.

Materials And Methods: We enrolled high-risk patients for VTE (based on Caprini score) in the general surgery ward.

Determinants of mortality in patients with traumatic brain injury.

Background: We aimed to determine factors associated with mortality rates in patients with traumatic brain injury (TBI).

Methods: Registered data of a national trauma project conducted in eight major cities in Iran during a five-year period were used. Patients with a TBI were identified and both univariate and multivariate analyses were performed.
